Periodically get ‘device not responding’ error on my HiveOS rig

Once a 2 or 3 minutes I get the following error in the miner log:

grep -i error /var/log/miner/gminer/gminer.log
Error on GPU6: Device not responding, check overclocking settings

and on the following message on the miner screen:

miner
GPU6: DAG has been damaged, check overclocking settings
Miner terminated, watchdog will restart process after 10 seconds

GPU temperature is about 50-60°C, but looks like the memory chips overheat, because there was NVidia error:

Some GTX 1060 3GB cards have low hashrate with Ethash coins.

Ethash algorithm behaves a bit strange on my mining rig with HiveOS and 8 GTX 1060 3GB. Four MSI ARMOR cards with Sumsung memory (OC +1500 mem) have 24+ MH/s, two other cards (OC +600 mem) have 21+ MH/s and two other slow MSI cards (also OC +600 mem) have only 18+ MH/s. I tried to switch risers, PSU, PCI slots and move the cards across rigs, but with no success.

Today I did a pure experiment. I plugged one of the slow cards to a Windows 10 machine with 1000W PSU directly via PCI slot without riser, started Claymore Miner with Musicoin (that has a lower dag size than Ethereum) and got the same result as before, without OC the card had 15+ MH/s (normally it should be 19+ MH/s):

Molten SATA power connector on a mining rig.

I have a mining rig with 8 GTX 1060 3GB connected via risers, the risers are connected via SATA power connectors to Corsair HX850. When the rig stopped working I noticed that one SATA connector on the PSU is molten:

Mining Ethereum on Ubuntu 18.04 with GeForce GTX 1060 3GB

I am not a Linux expert, so it took me some time to configure my mining rig on Ubuntu 18.04 with NVIDIA GeForce GTX 1060 3GB, and I wrote down all the steps I did:

First I installed NVIDIA driver, but OpenCL did not install automatically with it and I installed it manually with the following command:

sudo apt install -y ocl-icd-libopencl1

Then I installed CURL:

sudo apt install -y libcurl3

not ‘curl’ and not ‘libcurl4’ packages, otherwise the miner will fail to start reporting the following error message:

./ethdcrminer64: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by ./ethdcrminer64)

ASUS H270M-PLUS Motherboard requires specific network driver for Windows 10.

Windows 10 does not find network driver for ASUS H270M-PLUS motherboard automatically and the driver supplied with the motherboard does not install showing the message “The Realtech network controller was not found. If deep sleep mode is enabled please plug the cable”. But there is some specific Intel(R) Ethernet Connection (2) I219-V driver that works fine:
